Sunshine can lift winter spirits, but skin still needs protection from UV rays.In Australia, high skin cancer rates compel students to slap on hats and sunscreen at recess year 'round. Now comes nanotechnology, the manipulation of matter at the tiniest molecular level. It's used in developing scores of surprising products--including sunblock, as this week's activity reveals. Will your sun worshippers see promise or peril? Speaking of summer, check out these cool engineering programs for students and  teachers, including one sponsored by ASEE . 


Lesson: Explore Nano Sunblock 


nano lessonSunblocks containing nanoparticles are one of the most common applications of nanotechnology. In this quick, hands-on lesson using everyday materials, students in grades K-12 compare sunblock containing nanoparticles to those that do not and learn how nanoparticles are used to help block harmful rays from the sun.
